S82.421A Displaced transverse fracture of shaft of right fibula, initial encounter for closed fracture

Name of the Condition

• Displaced transverse fracture of shaft of right fibula, initial encounter for closed fracture
• ICD-10 Code: S82.421A

Summary

A displaced transverse fracture of the shaft of the right fibula is a break in the long, thin bone on the lateral side of the lower leg, where the bone fragments are separated and misaligned. This is a closed fracture, meaning the skin remains intact, and it is the initial encounter for treatment. The transverse pattern indicates the fracture line runs horizontally across the bone.

Causes

Most commonly caused by direct trauma or impact to the leg, such as from falls, sports injuries, or motor vehicle accidents. High-force impacts or twisting motions can also lead to this type of fracture.

Risk Factors

• Participation in contact sports or high-impact activities.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.
• Previous leg injuries or surgeries.

Symptoms

• Pain and swelling in the lower leg.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Possible deformity or instability of the leg structure.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture, determine its extent, and evaluate alignment.

Treatment Options

• Immobilization of the leg using a splint or cast to allow the bone to heal properly.
• Pain management with medications such as analgesics.
• Physical therapy to restore movement and strength after healing.

Prognosis and Follow-Up

Most displaced transverse fractures of the fibula heal well with appropriate treatment. Follow-up care may include monitoring for proper healing and gradual return to weight-bearing activities. Long-term outcomes depend on the severity of the fracture and adherence to treatment plans.

Complications

• Delayed healing or nonunion of the fracture.
• Malunion, where the bone heals in an improper position.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or stiffness in the leg.

Lifestyle & Prevention

• Wear appropriate protective gear during sports or high-risk activities.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid activities that increase the risk of falls or direct leg impacts.
• Strengthen leg muscles to improve stability and reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, warmth, or pus) at the injury site.

Tips for Medical Coders

Document the fracture type (displaced, transverse), location (shaft of right fibula), and encounter type (initial for closed fracture) to ensure accurate coding. Include details on alignment, skin integrity, and any associated injuries to support the code selection.
